well, since we're talking about graphics... the transition to 3D in the fifth installment was successful, but I agree with those who miss the graphics of the third game. It's simply the only part of the series where the artwork is less cartoonish and more serious, if you will. Those who don't understand what I'm talking about should look at how the manticores are made in the fifth game =)
if it was technically impossible in the second game, then today's developers had a choice - and it's a pity that they chose a cartoon style...
but that's something that could only be done within the framework of the previous world...
